Liquid crystal display television is, as indicated by its name, a television using LCD technology (generally TFT), as opposed to cathode ray or plasma for its visual output.
Early LCD panel television had some difficulties displaying fast-moving action and had quite restricted viewing angles. These problems have largely been overcome in recent years, and the market for LCD televisions is booming, especially in Asia. For a long time it was widely believed that LCD technology was suited only to smaller sized televisions, and could not compete with plasma technology at larger sizes. This belief has been undermined by the announcements of ever-larger panels by companies such as Sharp Corporation, Samsung and LG.Philips. In October 2004, 40" to 45" televisions were widely available and Sharp Corporation had announced the successful manufacture of a 65" panel. Also in 2004, Samsung and Sony joined forces to build a factory in South Korea, intended to produce 60,000 panels a month. The main manufacturers have all pledged to invest billions of dollars in LCD production over the next few years, with televisions expected to be a key market.
Perhaps the best-known brand of LCD televisions at present is Sharp's Aquos range.
Modern LCD TV sets are geographically universal because they have a multisystem tuner, to display PAL, NTSC and SECAM norms. And they include an electronic (step-down & step-up) transformer that automatically can use 110/200 V AC indiferently and universal grounded adapter plugs.
They are not only for old TV and HDTV (DVB), because they can display VGA/DVI and can be used like a computer monitor at the same time.
